Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-6 A modular composite panel for railway vehicles, comprising:

[0034] The base plate 100 serves as the basic support structure for the composite panel, bearing the overall weight of the composite panel and various loads from the vehicle operation process. It provides a stable installation foundation for other components and ensures the structural stability of the composite panel under complex operating conditions of railway vehicles.

[0035] Panel 200 is located on one side of base plate 100. Panel 200 is directly exposed to the external environment. Its main function is to protect the internal structure while meeting the vehicle's exterior decoration requirements.

[0036] There are two assembly plates 400, which are installed between the base plate 100 and the front panel 200. The two assembly plates 400 are symmetrically arranged. The two symmetrically arranged assembly plates 400 are the core components for realizing the rapid assembly of composite panels, simplifying the installation process and improving installation efficiency. The symmetrical design ensures that the plug plate 201 is subjected to uniform force and enhances the overall stability.

[0037] The plug-in plate 201 is installed on the panel 200. The plug-in plate 201 is installed between two assembly plates 400. It is installed on the panel 200 and located between the two assembly plates 400. By cooperating with the assembly plates 400, it realizes the quick plug-in assembly between the panel 200 and the base plate 100, avoiding the traditional drilling installation method, simplifying the assembly process, and reducing installation time and labor costs.

[0038] Reference Figure 4 and Figure 5 A fixing plate 401 is installed on the side of the base plate 100 near the panel 200. Adjustment grooves are provided on the sides of the two assembly plates 400 that are close to each other. The fixing plate 401 is set in the two adjustment grooves. The two assembly plates 400 can move on the fixing plate 401 to adjust the distance between the two assembly plates 400. This can accommodate panels 200 and plug-in plates 201 of different thicknesses.

[0039] Reference Figure 5 Bolts 402 are installed on the assembly plate 400 and the fixing plate 401. The assembly plate 400 and the fixing plate 401 are connected to the base plate 100 by the bolts 402. After determining the fixing plate 401 and the distance between the two assembly plates 400, the fixing plate 401 and the assembly plate 400 can be fixed to the base plate 100 by the bolts 402. Then, the plug plate 201 on the panel 200 is directly inserted between the two assembly plates 400 to complete the assembly.

[0040] Reference Figure 5 The assembly panel 400 includes:

[0041] A groove 405 is formed on one side of the assembly plate 400 to accommodate the limiting plate 403 and the limiting strip 404, providing guidance and limiting space for the insertion of the plug plate 201;

[0042] A limiting plate 403 is installed in a groove 405. A limiting strip 404 is installed on one side of the limiting plate 403. The limiting strip 404 is used to limit the insertion plate 201. The limiting plate 403 and the limiting strip 404 are used to limit and fix the inserted insertion plate 201, prevent the insertion plate 201 from loosening or falling off during use, enhance the reliability of the connection between the insertion plate 201 and the assembly plate 400, ensure that the composite plate will not fail at the insertion part due to vibration or other factors during vehicle operation, and improve the overall structural stability of the composite plate.

[0043] Reference Figure 5 and Figure 6A snap-fit ​​strip 202 is installed on one side of the plug-in plate 201. The snap-fit ​​strip 202 is adapted to the limiting strip 404. The snap-fit ​​method enables the plug-in plate 201 to be quickly connected and fixed to the assembly plate 400, which simplifies the installation process of the plug-in plate 201, realizes quick and convenient assembly, and provides reliable connection strength to ensure the stability of the composite panel assembly structure.

[0044] Reference Figure 5 An elastic element 406 is installed on the inner wall of the groove 405. The elastic element 406 is connected to the limiting plate 403 and provides elastic support for the limiting plate 403. When the plug plate 201 is inserted, the elastic element 406 is compressed by force. After the insertion is completed, the elastic element 406 restores its deformation and tightly locks the plug plate 201. The elastic element 406 can be a sheet or a spring.

[0045] Reference Figure 6 The number of limiting strips 404 is several, and one side of the limiting strip 404 is formed with a slope. The slope facilitates the insertion of the plug plate 201 to guide the snap-fit ​​strip 202 and reduce the insertion resistance.

[0046] Reference Figure 1 A sound insulation board 300 is installed between the base plate 100 and the panel 200. The sound insulation board 300 effectively reduces the interference of external noise and vehicle operation noise to passengers, and meets the requirements of railway vehicles for sound insulation performance.

[0047] The plug-in plate 201 is disposed at the end of the panel 200, and the panel 200 and the plug-in plate 201 are L-shaped.

[0048] The assembly plate 400 has an L-shaped cross-section, which allows it to better fit with the base plate 100 and the panel 200, while providing installation space and support structure for other components.

[0049] During use, the fixing plate 401 is installed on the side of the base plate 100 near the panel 200 as the installation reference for the assembly plate 400. Two L-shaped assembly plates 400 are installed between the base plate 100 and the panel 200 respectively, placed symmetrically, and the adjustment groove on the assembly plate 400 is fitted onto the fixing plate 401. At this time, the assembly plate 400 can move along the fixing plate 401. The fixing plate 401 and the assembly plate 400 are temporarily fixed to the base plate 100 by bolts 402, but not tightened, so that the assembly plate 400 can be freely adjusted on the fixing plate 401.

[0050] Based on the actual thickness of the panel 200 and the plug-in plate 201, the position of the two assembly plates 400 on the fixed plate 401 is moved to adjust the spacing between the two assembly plates 400 to ensure that the spacing matches the size of the panel 200 and the plug-in plate 201. After the spacing is adjusted, the bolts 402 are tightened to firmly fix the fixed plate 401 and the assembly plates 400 on the base plate 100. The position of the assembly plates 400 is determined, and the sound insulation plate 300 is installed between the base plate 100 and the panel 200 to complete the internal sound insulation structure setting.

[0051] Insert the plug-in plates 201 on the two panels 200 between the two assembly plates 400. Using the inclined surface on one side of the limiting strip 404 as a guide, during the insertion process, the snap-fit ​​strip 202 of the plug-in plate 201 squeezes the limiting strip 404, pushing the limiting plate 403 to compress the elastic element 406 on the inner wall of the groove 405. When the snap-fit ​​strip 202 passes the limiting strip 404, the elastic element 406 restores its deformation, pushing the limiting plate 403 to make the limiting strip 404 lock the snap-fit ​​strip 202, thus completing the snap-fit ​​fixing of the plug-in plate 201 and the assembly plate 400, and realizing the rapid splicing of the panel 200 and the base plate 100.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
